yet another round around teh BluRay muxing
by Andrew Randrianasulu 09 Nov '19

09 Nov '19

https://github.com/justdan96/tsMuxer ============ tsMuxer Vision This project is for tsMuxer - a transport stream muxer for remuxing/muxing elementary streams. This is very useful for transcoding and this project is used in other products such as Universal Media Server. EVO/VOB/MPG, MKV/MKA, MP4/MOV, TS, M2TS to TS to M2TS. Supported video codecs H.264/AVC, H.265/HEVC, VC-1, MPEG2. Supported audio codecs AAC, AC3 / E-AC3(DD+), DTS/ DTS-HD. Some of the major features include: Ability to set muxing fps manually and automatically Ability to change level for H.264 streams Ability to shift a sound tracks Ability to extract DTS core from DTS-HD Ability to join files Output/Author to compliant Blu-ray Disc or AVCHD Blu-ray 3D support Language tsMuxer is written in C++. It can be compiled for Windows, Linux and Mac. History This project was created by Roman Vasilenko, with the last public release 20th January 2014. It was open sourced on 23rd July 2019, to aid the future development. ============= Threads I used for finding this: https://forum.doom9.org/showthread.php?t=176668 https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/issues/11

blu-ray muxing in mpegts
by Andrew Randrianasulu 08 Nov '19

08 Nov '19

Well, I was looking at why https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blob;f=cinelerr… failed to apply (it does some fixes to ffmpeg's mpeg2ts muxer). I can't figure out what parts of this patch still must be applied to ffmpeg master, but I found few ffmpeg tickets, related to some problem this patch probably tries to answer (CinlerraGG supports making Blu-Ray disks, even if in limited way) https://lists.mplayerhq.hu/pipermail/ffmpeg-user/2017-January/035013.html ------ >> So far I have therefore given up to get pcm audio muxed into .m2ts >> for a working Blu-ray video. > Just to avoid a misunderstanding: > From FFmpeg's pov, "pcm" and "pcm-bluray" are two completely > different things like - for example - h264 and vp8; and on this > mailing list only FFmpeg's pov makes sense imo. > Muxing pcm in mpegts in impossible, this is not a limitation of FFmpeg. > Muxing pcm-bluray (and bluray subtitles) in mpegts is also impossible > with FFmpeg, this is ticket #2622. ------------ https://trac.ffmpeg.org/ticket/2622 Subtitle (hdmv pgs) remux fails for some reason more generic ticket mentioned there just closed as duplicate? https://trac.ffmpeg.org/ticket/7842 M2TS muxer doesn't generate valid Blu-Ray files I'm not sure what "The reason that FFmpeg does not support muxing pgs in mpegts is that FFmpeg does not support writing m2ts files" phrase mean? Because m2ts writing IS here, just not complete ..... Yes, CinGG patch doesn't deal with subtitles. And I don't understand patch, but it is here, or even version against ffmpeg-4.2: https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blob;f=cinelerr… should I try to post this to ffmpeg's ticket 7842 ? I don't have real BluRay player, so I can't test resulting files ...

UPD: Is audio opts file for m2ts usable?
by Andrew Randrianasulu 08 Nov '19

08 Nov '19

ah, it was just due to missing patch (one failing to apply to ffmpeg.git) please discard this false alarm message. ---------- Пересланное сообщение ---------- Тема: Is audio opts file for m2ts usable? Дата: Пятница 08 ноября 2019 Отправитель: Andrew Randrianasulu <randrianasulu(a)gmail.com> Получатель: "Cinelerra.GG" <cin(a)lists.cinelerra-gg.org> I tried to render blu--ray profile (ffmpeg-m2ts type) and while video worked - audio was giving me troubles .. I changed bluray ac3 at very beginning of /usr/share/cin/ffmpeg/audio/bluray.m2ts to mpegts ac3 , now sounds apparently works (no render error, mplayer show audio stream with 192 Kbit/s bitrate) but is this right fix, or bluray keyword used internally for cin for Blu-Ray profiles? If this is right fix - there are some video opts files where format defined as "bluray libx264" at the top of the file: bluray.m2ts bluray_dv_ntsc.m2ts bluray_dv_pal.m2ts bluray_lo.m2ts visually_lossless.m2ts I think I made those files work as render choice, but BD creation not tested yet .... may be bluray.m2ts from audio folder should be renamed bluray_ac3.m2ts ? -------------------------------------------------------

https://git.ffmpeg.org/gitweb/ffmpeg.git/history/HEAD:/libavformat/mpegtsen… avformat/mpegtsenc: fix incorrect PCR selection with multiple programs avformat/mpegtsenc: factorize setting up services avformat/mpegtsenc: remove section_write_packet forward declaration avformat/mpegtsenc: use increasing numbers in default service names avformat/mpegtsenc: fix PCR generation intervals avformat/mpegtsenc: remove deprecated resend_headers option avformat/mpegtsenc: rename pcr_period variable to pcr_period_ms avformat/mpegtsenc: add support for setting PCR interval for VBR streams avformat/mpegtsenc: move some code around and simplify a bit avformat/mpegtsenc: get rid of packet counting for sdt/pat/pmt avformat/mpegtsenc: fix flushing of audio packets lavf/mpegtsenc: fix logic check error so, as far as I understand this area ..this mean mpegtsenc patch in CinGG can be simplified now ... but sadly not by me, I still very much idiot when it comes to those complex areas

Quicktime and beginning of digital video editing era [article from 2013]
by Andrew Randrianasulu 04 Nov '19

04 Nov '19

Because I keep forgotting where _exactly_ I saw this article ..... http://basalgangster.macgui.com/RetroMacComputing/The_Long_View/Entries/201… scroll down to Quicktime Does it All (but you can read whole thing if you like) --------- Quicktime was basically a complete library for creating video editing programs. It included standard code for selecting a video digitizer, copying and pasting movies, even setting a selection in a movie (effectively setting in and out points for an edit), and cutting or copying only that selection. It included built-in support for superimposing styled text on movies, and even for scrolling text to make titles and credits. All that made it much bigger than other Apple APIs at the time. In fact it was not one API, but rather a collection of them. -------- So, basically it explains existence of controls you can see for example in ffmpeg-4.2/libavformat/mov.c : static const AVOption mov_options[] = { {"use_absolute_path", "allow using absolute path when opening alias, this is a possible security issue", OFFSET(use_absolute_path), AV_OPT_TYPE_BOOL, {.i64 = 0}, 0, 1, FLAGS}, {"seek_streams_individually", "Seek each stream individually to the to the closest point", OFFSET(seek_individually), AV_OPT_TYPE_BOOL, { .i64 = 1 }, 0, 1, FLAGS}, {"ignore_editlist", "Ignore the edit list atom.", OFFSET(ignore_editlist), AV_OPT_TYPE_BOOL, {.i64 = 0}, 0, 1, FLAGS}, {"advanced_editlist", "Modify the AVIndex according to the editlists. Use this option to decode in the order specified by the edits.", OFFSET(advanced_editlist), AV_OPT_TYPE_BOOL, {.i64 = 1}, 0, 1, FLAGS}, {"ignore_chapters", "", OFFSET(ignore_chapters), AV_OPT_TYPE_BOOL, {.i64 = 0}, 0, 1, FLAGS}, {"use_mfra_for", "use mfra for fragment timestamps", OFFSET(use_mfra_for), AV_OPT_TYPE_INT, {.i64 = FF_MOV_FLAG_MFRA_AUTO}, -1, FF_MOV_FLAG_MFRA_PTS, FLAGS, "use_mfra_for"}, {"auto", "auto", 0, AV_OPT_TYPE_CONST, {.i64 = FF_MOV_FLAG_MFRA_AUTO}, 0, 0, FLAGS, "use_mfra_for" }, {"dts", "dts", 0, AV_OPT_TYPE_CONST, {.i64 = FF_MOV_FLAG_MFRA_DTS}, 0, 0, FLAGS, "use_mfra_for" }, {"pts", "pts", 0, AV_OPT_TYPE_CONST, {.i64 = FF_MOV_FLAG_MFRA_PTS}, 0, 0, FLAGS, "use_mfra_for" }, { "export_all", "Export unrecognized metadata entries", OFFSET(export_all), AV_OPT_TYPE_BOOL, { .i64 = 0 }, 0, 1, .flags = FLAGS }, { "export_xmp", "Export full XMP metadata", OFFSET(export_xmp), AV_OPT_TYPE_BOOL, { .i64 = 0 }, 0, 1, .flags = FLAGS }, { "activation_bytes", "Secret bytes for Audible AAX files", OFFSET(activation_bytes), AV_OPT_TYPE_BINARY, .flags = AV_OPT_FLAG_DECODING_PARAM }, { "audible_fixed_key", // extracted from libAAX_SDK.so and AAXSDKWin.dll files! "Fixed key used for handling Audible AAX files", OFFSET(audible_fixed_key), AV_OPT_TYPE_BINARY, {.str="77214d4b196a87cd520045fd20a51d67"}, .flags = AV_OPT_FLAG_DECODING_PARAM }, { "decryption_key", "The media decryption key (hex)", OFFSET(decryption_key), AV_OPT_TYPE_BINARY, .flags = AV_OPT_FLAG_DECODING_PARAM }, { "enable_drefs", "Enable external track support.", OFFSET(enable_drefs), AV_OPT_TYPE_BOOL, {.i64 = 0}, 0, 1, FLAGS }, { NULL }, }; Not sure if any of those more advanced options actually used now by CinGG, but they are there :} Another thing i found, about DV (a bit old, like from 2006 at best, still historical perspective I like to read (more than code!): https://www.adamwilt.com/DV-FAQ-tech.html by Adam J. Wilt. (analog TV was strange and complicated thing ...) Random site with historical video editing machines (incl. CMX): http://www.vtoldboys.com/editingmuseum/index.htm

UPD: Current CinGG git fails to build with current ffmpeg.git, but may be this is not a problem yet

moving patch to NO_patch with mv right before configure stage solved patching problem, so build continues .. # temporariry remove ffmpeg.git patch #2 mv thirdparty/src/ffmpeg.git.patch2 thirdparty/src/NO_patch from slackbuild I modified I wonder what exactly this patch was trying to workaround, some long-duration dvb->blu-ray transcoding? As far as I understand usual practice when upstreaming (or asking for comments on) patches is to make one thing per patch, even if it will made their number grow. I'm not a programmer, so I am puzzled even by beginning of patch: https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blob;f=cinelerr… - int pcr_pid; - int pcr_packet_count; - int pcr_packet_period; + int64_t pcr, pcr_packet_timer, pcr_packet_period; + int pcr_sid, pcr_pid; does this mean int was not big enough? and end a bit puzzling for me too, i see new options added but I can't reformulate why they were needed..? + { "mpegts_pcr_start_pid", "Set the first pid of the PCR.", and more + { "mpegts_pcr_offset", "clock offset.", real developers probably will understand what those must do, but I usually try to understand something so I can make some slightly more intelligent noise about it .... ---------- Пересланное сообщение ---------- Тема: Current CinGG git fails to build with current ffmpeg.git, but may be this is not a problem yet Дата: Понедельник 04 ноября 2019 Отправитель: Andrew Randrianasulu <randrianasulu(a)gmail.com> Получатель: cin(a)lists.cinelerra-gg.org I remember those git patches updated mostly ar ~rc/branching (for ffmpeg) time, I just tried my luck one more time and yeah ... nope: patch -d ffmpeg* -p1 < src/ffmpeg.git.patch1 patching file libavformat/bluray.c patch -d ffmpeg* -p1 < src/ffmpeg.git.patch2 patching file libavformat/mpegtsenc.c Hunk #1 FAILED at 56.

Probably I should revisit this at ffmpeg 4.3's rc time. Just for your information. -------------------------------------------------------
